After Upgrade SugarCRM with 12.3. Portal configuration are not changed

Hi,

Recently I have upgraded SugarCRM 9.* to 12.3 after upgrade when I checked portal configuration page looks like it's older one. It is not upgraded with 12.3. Please check the image.

Any one has experience the same issue?

New design should be looks like this. 

Because of this issue our portal is not working as expected.

Thanks & Regards,
